Getting this error only in new 8.4.0 version after requiring firebase like so:

var firebase = require("firebase/app");
require("firebase/auth");
require("firebase/database");

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Same issue when using import 'firebase/database', dropping down to v8.3.3 solved the issue immediately.

./node_modules/@firebase/database/dist/index.esm.js Module not found: Can't resolve '@firebase/app-exp' in '/home/derek/projects/test2/node_modules/@firebase/database/dist'

It is now fixed in 8.4.1.
